Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION DEL GEL SIO2 MODIFICADO, CONOCIDO COMO "XEROGEL", ASI COMO EL XEROGEL ASI ELABORADO Y SU UTILIZACION. LOS XEROGELES SON ELABORADOS DE TAL MODO, QUE SE ACIDIFICA UNA SOLUCION DE VIDRIO SOLUBLE ACUOSA, SIENDO POLIMERIZADO EL ACIDO SILICICO GENERADO MEDIANTE LA ADICION DE UNA BASE PARA FORMAR UN GEL SIO2, CON UN DISOLVENTE ORGANICO LAVANDO AMPLIAMENTE CON AGUA A PARTIR DEL GEL, TRANSFORMANDOSE CON UN MEDIO DE SILIZACION Y SECANDOSE ENTONCES EN UNA TEMPERATURA DESDE -30 HASTA 200 SION DESDE 0,1 HASTA 20 BAR.
